DEQDORIZER.

Application filed october 179, 1921. Serial No. 508,674.

T0 all whom. t may concern Be it known that l, CHARLES la. Wim., a citizen of the United States, residing at St. Louis, Missouri, have invented a new and useful Deodorizer, of which the following is a specification. o i

lThis invention relates to deodorizers.

An object of the invention is to provide a deodorizer of novel and eHicient construction for commercial use, including means for rendering the fumes combustible, and means for eecting combustion of the fumes and discharging the products of combustion to atmosphere.

Another object of the invention is to pro vide an improved deodorizer for commercial use, including a building or enclosure for' confining the fumes, a stack or passage from the building or enclosure through which the fumes are caused to pass, means for rendering the :fumes combustible during their passage through the stack, and means for efecting combustion of the combustible fumes and discharging the products of combustion to atmosphere.

Another object of the invention 1s to provide means for causing the fumes to pass through the passage in which combustion is effected.

@ther objects will appear from the fol lowing description, reference being made to the drawing in whichlig. l is a vertical sectional view showing one embodiment of my improved deodorizer.

Fig. 2 is a cross sectional view of the stack on either of the lines 2-2 of Fig. l.

Fig. 3 is a cross sectional view of the stack on the line 3--3 of Fig. l.

Fig. l is a cross sectional view of the stack on either of the lines Lil-1l of Fig. l.

Fig. is a cross sectional view of the stack on the line 5-5 of F ig. l.

Vlin the embodiment of the invention shown the building or enclosure for coniining the odors comprises a supporting foundation l and a dome-like roof or cover 2 from the top of which a stack 3 extends upwardly to a desired height for the discharge of the products of combustion after the fumes have been burned. The wall of the dome or en# closure Q, has a number of ventilamr openings l near the `foundation for the admission of pure air in order to cause the fumes to rise to the top of the dome-like enclosure and to pass upwardly through the stack 3. The openings l may be opened or closed as desired andv by any suitable means, as by a sliding door or doors 5 mounted in guides 6 and movable therein to and from positions to open and to close the air inlet openings 4. Within the stack 3 some distance above the point at which the dome opens into the stack a number of grids, breaks or baii'les are supported in order to break up the fumes and the vapors for more perfect mixture with the combustible chemical or other material which is injected into the stack for mixture with the fumes and vapors preparatory to combustion. As shown two of these grids, breaks or baffles are in the form of discs 'l' supported within the stack by brackets or arms 8 in connection with the st ack and engaging extended portions on the discs. lThus an annular space is left around each of the discs 7 between the peripheral edges of said discs and thewall of the stack 3. Each of the discs 7 is also formed with numerous perforations or holes 9 through which a part of the fumes or vapors pass, while the remainder of the fumes or vapors pass through the circular space between the discs and the stack wall.

Between the discs 7' another disc l0 is supported, as by brackets il` in connection with the stack upon which the disc rests. The disc l0 is formed with a relatively large central opening i2 surrounded by series of smaller openings i3.

lit is apparent that as the fumes pass up2 wardly through the stack 3 and through or around the grids, breaks or baffles, said iiumes will become broken or separated and caused to circulate. Between the lower grids or battles and above the upper one masses oi fibrous or felt like material 1l.EL are located to aid in the circulation of the fumes and the mixing of the combustible chemical therewith. As the fumes circulate they are rendered combustible by the injection therein and mixtureotherewith of a combustible chemical or other material injected through nozzles la in connection with branchesl opening into a supply pipe 16. The nozzles extend some distance into the stack and into ther material ll above the respective grids, breaks or baos so that while the fumes and odors are in circulation a complete mixture is ei'lected.

At a suitable height along the stack 3 and above the chemical mixing device the combustion apparatus is located. The combustion apparatus may be of any appropriate lll@ , the form of three burners, the upper and lower ones of which are substantially alike, each including crossed burner arms 17 having openings 1n their lower sides for the 1njection of the combustible gas. The intermediate burner comprises crossed. burner arms 18 which, however, extend in different directions from the directions in which the burner arms 17 extend.

The burners are supported within the stack and are supplied with fuel from branches 19 extending from a fuel supply pipe 20.

Doors 20a may be provided in the stack for affording access to the inside to repair or give attention to any of the parts therein.

Within the dome-llike enclosure 2 and below the opening'in the stack 3 a pan or receptacle 21 is supported upon brackets 22 in order to receive ,and retain any substances dropping from the stack. A'drain pipe 21a extends` downwardly from a drain opening in the bottom of the pan 21 to drain off the contents or accumulations. encircled by la burner 23 communicating wlith and supplied with gas by the pipe 20.

The burner 23 located near the top of the room or enclosure formed by the dome 2 vand near the opening into the stack cooperates with lthe burners 17 and 18 near the top of the stack in order to create a draft to cause the fumes to rise into the stack and to circulate through the grids, breaks or baffles, t'o become mixed with the chemicals injected through the nozzles 14, and to pass on through the burners near the top of the stack where deodorization is completed. The pure air admitted into the room' through the openings 4c and under control of the closures 5 aids the operation, as pure air is admitted to replace the air bearing the fumes that rises through the stack and is discharged in a purified and deodorized condition therefrom.

From. the foregoing it will be seen that my invention completely obtains all of lits intended objects and purposes. It is practicable for commercial use and may be used satisfactorily in connection with any enterprise (packing houses for instance) in which obnoxious fumes are created. The fumes being subjected to heat and inc lineration are purified so that when the air passes from the stack all obnoxious characteristics are completely eliminated.

It is apparent that my invention may be widely varied in the construction and arrangement of the parts without departure from the nature and principle thereof. 1 contemplate such variations as may be necessary or desirable to adapt the 1nvention to various uses, or for use in connection with Various enterprises and industries. l
